Abstract

Background: Left ventricular outflow tract pseudoaneurysm is a rare but potentially fatal complication of aortic valve replacement, infective endocarditis, and suture dehiscence. Left ventricular-aortic discontinuity is a severe and uncommon manifestation of IE. For patients who have a long-standing history of endocarditis, peri-annular lesions in the aortic valve may rupture, leading to the rare occurrence of complete, or total, left ventricular-aortic discontinuity. Methods: We present a case of complete postoperative left ventricular-aortic discontinuity and massive circumferential left ventricular outflow tract pseudoaneurysm discovered during a 3-month follow-up visit. Results: Post-operative cardiac CT of a patient demonstrated dehiscence of a recently placed surgical aortic valve from the left ventricular outflow tract, with massive circumferential pseudoaneurysm formation. Only a small remnant of the membranous interventricular septum connected the aortic root to the heart, informing the diagnosis of complete left ventricular-aortic discontinuity. Conclusion: The clinical presentation of a left ventricular outflow tract pseudoaneurysm with concomitant left ventricular-aortic discontinuity is commonly nonspecific or clinically silent; thus, it requires a high index of suspicion and use of multimodality imaging for diagnosis and management.
